DEMOUNTABLE RIM.

Specification of Letters Patent.

Patented Nov. 16. 1920.

Application filed December 20, 1918. Serial No. 267.627.

To all whom it may concern Be it. known that I, GERALD G. BARRY, a citizen of theUnited States, and a resident of Chicago, in the county of (ook and State of Illinois, have invented certain new and useful Im rovements in Demountable Rims for Vehic e-Tires, of which invention the following is a specification.

Demountable rims are now being quite generally employed with automobile wheels, enlibling the removal from the wheel of both the tire and the rim carrying the same when repairs are needed and the replacement thereof by a fully inflated and mounted extra tire which is carried. Although this permits the further task of removing the fire from the rim and again rephr-ing some to be put off, nevertheless that generally arduous and ei'msperating task remains to be performed, and is res )onsible for the ex penditure of a great (cal of time and ener in using ordinary rims; and this not.-

some improvements have been made, named rather unwarrantably, however, quick-detachable.

The resent invention has for its object the ma in of this task of positioning or removing 51o tire on easy one, and the in vention' consists in the rovision of a slumture which is cheap an simple to manufacture, requires no change in the established tire and wheel sizes, and is adapted to be veryreadily positioned or withdrawn from operative mounted relation with the tire.

The manufacturers and users of rims will readily upprermtethe advantages of the improvements provided by the present invention from a consideration of the description of same in this specification thereof, together with the acoompan mg drawings orniing a part of the SpQll ration.

Referring to the-accompanying drau ings,-Figure 1 is a. side elevation. showing the new collapsible rim,some parts broken awa to ex 1088 details, with the outline of a w eel body on which the rim may be demountably secured dotted in, the rubber tire carried by the rim in the complete wheel structure, however, not being shown.

Fig. 2 is a face view of a part. taken on the line-22 of Fi 1, showing adjoining seetions of the rim use band at one of the transverse partings umted'b a hinge, the opposite arms ofthe hin e em secured to the adjoining ends of-t e sections of the rim blind by rivets or otherwise; this view also showing the abutting ends of the side flanges, which project outwurdlv from the base band and embrace the tire seats, to be flared near the top in order to provide increased abutment surface.

Fig. 3 is a view looking down upon the simple locking device preferably employed for detachably securing the adjoining ends of the rim sections at one of the transvers partings.

Fig. 4 is a section on the line 4-4 of Fig. 1. taken at the renter of one of the h nged partings, showing the way the limited space is utilized. also showing the Hare which may be iven to the abutting flange ends.

I ig. 5 is a view showing a modified form of hinge means of swinging the sections innow on the market, including some having.

one transverse split provided with a locking device of some sort, adapted when de mounted to permit the adjoining ends of the one-split ring to be sprung apart or drawn apart by special tools; Butwith most rims now on the market it is still necessar to perform some more or less diflioultwprh of prying and hgnmmering, with possible injury to the cas g and inner tube, before the tire can be positioned on or removed from the rim. The present invention providesa rim which is subdivided into a pluralityof sections. and udaptedto be easily collapsed and quite rezulily phsitioned or removed, without the aid of any special tools-or requiring prying and hammeririg and injury to the tire.

Referring t the drawings now more in detail, Fi 1 il ustrntes the rim structure to be sectiomzed into three substantially ual portions of its circumference, and instea of there being onl one transverse parting slit, such as marke here at a, rovided with a detachable locking means, t ere are two additional transverse slits parting the rim, as indicated at a and a, the sections ofthe Lin rim being here marked a, a and a. At the two additional iartings a and a Suitable hinge means, Qltl'ittfli B i provided. uniting adjoining ends of aertions ot' the rim, th ends at the rvmaining parting a} being detarrhabiy set-uteri hp a locking device, e1cmeat C.

This; t'tillfllith' in varying the transrvrsv part in slit from one on a true radim lino of tinrim. as at It and a, to a morn irrt gnlar out. as shown at tho parting a in Fig; l and Fin. 3. The jnm'tion lint: through the sido flangis lltl't is on a morn ohlit no angjln. whirl: may rvvvdu at the base hand, so that the adjat-vnt ends of the base band and flanges have abutting engagement with section a resting on and supported by a, and thus, with the abutting conta t of the flanges at the partings a and u), there can be no outward yielding without forcibly springing the circle, which is furthermore practically impossible when the tire is on the rim. To the section a is also pivoted a swingin arm or flat lock piece 0; see Fig. 3. hen this is swung around on the pivot and rests wholly on the section a, the parting slit between the base bands is uncovered and the two adjoining rim sections may be freed from abutting engagement and swung inwardly, or the reverse. It will be noticed that the more oblique angle of the slit through the side flanges here makes this operation much easier than it the parting was on a straight line the same as at a and a, while at the same time the other purpose of the close abutment of the flanges is served. The ends at the slit across the base band at this detachable parting may also have projecting points on one section end and receiving recesses therefor on the other end, as indicated at c, to prevent any lateral displacementralthough when the tire is in place on the run there is not much chance of this. \Vhen the section ends are brought into abutting relation and the pivoted arm 0 is swung around over the end of the section a, it will be noticed that the two sections are secured against disengagement. The arm 5 may also be provided with a downwardly projecting pivot head on the underside thereof, and the bands 0. and with a curved groove in whichgsuch projection 0 may travel when the arm a is being swung around from open to locked position, and when the arm is swung on to the end of the section a, across the parting slit, thisprojection on the arm, extending down such groove on the section, would prevent any possible springing of the rim cir('le.\ \dH0wever this is hardly necessary when the tire is in place on'the rim. Such whole assembly, however, makes a secure locking arrange ment.

In the foregoing I have described the invention in its preferred embodiment, but it will be obvious that various changes may be made in the constmction without departing from the spirit and scope of the invention. For example, various forms of locking devices may be employed in place of the more simple one I have here shown; also clencher type flanges may be used instead of. the "type for straight side tires I have here shown. I no not, therefore, wish any undue limitation to result from. the detailed description herein given, but desire the claims appended hereto to be construed as broadly as 'ossible in view of the prior art relating to r s.
